RELATED PATENT APPLICATIONS AND PATENTS

This application is a continuation-in-part of application for U.S. patent Ser. No. 760,085 filed on Oct. 24, 1991, now U.S. Pat. No. 5,175,175 issued on Dec. 29, 1992, which, in turn, is a divisional of application for U.S. patent Ser No. 691,638 filed on Apr. 25, 1991, now U.S. Pat. No. 5,091,423 issued on Feb. 25, 1992, which, in turn, is a divisional of application for U.S. patent Ser. No. 589,016 filed on Sep. 27, 1990, now U.S. Pat. No. 5,118,711 issued on Jun. 2, 1992.

BACKGROUND OF THE INVENTION This invention relates to the use of 1-octen-4-ol in repelling house flies (Musca domestica L.(Diptera:Muscidae)).

Compositions of matter taken alone or for use in combination with other perfumes for repelling house flies as well as apparatus used in determining such repellency have been indicated to exist in U.S. Pat. No. 4,759,228 issued on Jul. 26, 1988 (assigned jointly to International Flavors and Fragrances Inc. and The University of Florida). U.S. Pat. No. 4,759,228 discloses the use of 1-nonen-3-ol in repelling house flies. Furthermore, formulations exist in commerce which are said to provide adequate insect repellent properties, e.g., those set forth in U.S. Pat. 2,043,941 which indicates the repellency properties of methallyl disulfide and those set forth in U.S. Pat. No. 4,449,987 issued on May 22, 1984 which indicates the combination of methyl heptenones, coumarin and indole for use in perfumed candles.

Unsaturated alcohols other than 1-octen-4-ol and 1-nonen-3-ol and esters thereof are known with respect to controlling insects; and several have been found to attract insects and others have been found to repel such insects. Thus, U.S. Pat. No. 4,152,422 issued on May 1, 1979 sets forth 6-nonen-1-ol in a composition of matter used as an attractant for the male Mediterranean fruit fly.

Chem.Abstracts Vol.103, No.71086p concerns the synthesis of (Z)-8-dodecen-1-ol and its acetate as pheromone components of the Oriental Fruit Moth (Grapholita molesta). This is an abstract of the article in Acta Chem. Scan Ser. B, 1985, B39(4), pages 267-72. U.S. Pat. No. 4,364,931 issued on Dec. 21, 1982 discloses the use of 9(Z)-tetradecen-1-ol acetate in attracting male white-line dart moths.

Chem. Abstracts Volume 80, 1974, at No. 117098f discloses the use of trans-6-nonen-1-ol acetate as an ovipositional attractant and stimulant of the melon fly. U.S. Pat. No. 2,254,665 issued on Sep. 1, 1941, on the other hand, discloses the use of aliphatic alcohols having from 10 to 14 carbon atoms to repel insects. Examples of the aliphatic alcohols of U.S. Pat. No. 2,254,665 are all saturated alcohols, to wit:

dodecyl alcohol;

octyl alcohol;

hexadecyl alcohol;

tetradecyl alcohol; and

undecyl alcohol.

U.S. Pat. No. 2,254,665 fails to disclose the use of unsaturated alcohols in insect repellent compositions.

Chem. Abstracts Volume 74, 1974 at No. 99419f discloses various nonenyl acetates as attractants for female melon flies (abstract of J. Med. Chem. 1971, 14(3), pages 236-9) including trans-2-nonen-1-yl acetate.

On the other hand, Beroza, Materials Evaluated as Insecticides, Repellents and Chemosterilants at Orlando and Gainesville Fla., 1952-1964, Agriculture Handbook No. 340, published by The Agricultural Research Service, United States Department of Agriculture, August, 1967 discloses the following items 5443-5452 as insect repellents (on a scale of 1-10) as follows:

Item 5443--3-phenyl-2-octen-1-ol repels the yellow fever mosquitoes from cloth at a level of "1" on a scale of 1-10.

Item 5444--2,6-dimethyl-4-octen-3-ol repels the yellow fever mosquitoes from cloth at a level of "1" on a scale of 1-10.

Item 5445--3,6-dimethyl-5-octen-3-ol repels the yellow fever mosquitoes from cloth at a level of "1" on a scale of 1-10.

Item 5446--3-6-dimethyl-5-octen-3-ol acetate repels the yellow fever mosquitoes from cloth at a level of "1" on a scale of 1-10.

Item 5447--2,7-dimethyl-5-octen-4-ol acetate repels the yellow fever mosquitoes from cloth at a level of "1" on a scale of 1-10.

Item 5448--3,7-dimethyl-6-octen-1-ol repels the yellow fever mosquitoes from cloth at a level of "2" on a scale of 1-10.

Item 5449--3,7-dimethyl-6-octen-1-ol carbanilate repels the yellow fever mosquitoes from cloth at a level of "1" on a scale of 1-10.

Item 5450--3,7-dimethyl-6-octen-2-ol repels the yellow fever mosquitoes from cloth at a level of "1" on a scale of 1-10.

Item 5451--3,6-dimethyl-6-octen-3-ol repels the yellow fever mosquitoes from cloth at a level of "1" on a scale of 1-10.

Item 5452--3,7-dimethyl-6-octen-3-ol repels the yellow fever mosquitoes from cloth at a level of "2" on a scale of 1-10.

Beroza, Agriculture Handbook No. 340 at Item 7977 indicates that undecyl alcohol acetate has insect repelling properties as follows:

yellow fever mosquitoes: "1" on a scale of 1-10

tick at a level of "2" on a scale of 1-10.

Formulations exist in commerce which are said to provide candle body materials that are both perfuming and insect repellent but such formulations have yielded a candle body that is either insufficiently insect repellent or aesthetically displeasing from an organoleptic standpoint.

This is so, even though it was disclosed in U.S. Pat. No. 4,759,228 that 1-nonen-3-ol can be used in such candles to repel house flies (Musca domestica L. (Diptera:Muscidae)).

The properties of the repellent compounds of our invention have advantages which render the uses thereof unexpected, unobvious and advantageous over the use, of 1-nonen-3-ol.

When a candle burns, the heat of its flame melts a small pool of the candle body material around the base of the exposed portion of the wick, and this molten material is drawn up through the wick by capillary attraction to fuel the flame Thus, the process that takes place in the burning of a candle imposes rather stringent functional requirements upon the candle body material.

The material of a candle body must be rigid enough to support itself and a relatively long wick filament, but it should not be excessively brittle at low temperatures. Its melting point is critical in that it should liquify at temperatures to which it can be raised by radiant heat from the candle flame. If its melting temperature is too low, the candle will drip or, in an extreme case, the entire candle body will melt, dropping the wick into a pool of molten material with the hazardous possibility that the surface of the pool will ignite when this happens. If too high a temperature is required to melt the body material, the flame will be starved because insufficient fuel will be drawn up through the wick, with the result that the flame will be too small to maintain itself. When molten, moreover, the candle body material must have a relatively low viscosity in order to insure that it will be capable of being drawn up through the wick by capillary action.

In addition to meeting these requirements the candle body material must burn with a flame that is both luminous and smokeless and such odors as are produced by its combustion should not be unpleasant and should preferably be faint.

The functional requirements outlined above have, of course, been met by various candle body materials that are well known in the art, but heretofore no known materials that meet these requirements have been in combination:

(a) perfuming to the environment surrounding the burning candle;

(b) adequately insect repellent (both to house flies and mosquitoess) in the environment surrounding the material at various environmental temperatures at atmospheric pressure, from a temperature of about 0° C. up to a temperature of about 50° C.; and

(c) substantially so substantive that the perfuming property as well as the insect repellent property will last for a period of time well beyond the removal of the burning candle from the environment which is being perfumed and exposed to the insect repellent.

The 1-nonen-3-ol of U.S. Pat. No. 4,759,228 causes the environment surrounding the burning candle to be perfumed and adequately causes house flies to be repelled but does not act in an efficacious manner with respect to the desired environmental substantivity properties as set forth supra in Section (c).

U.S. Pat. No. 3,645,705 discloses a transparent candle body composition of matter which can contain:

a) from about 35% up to about 85% by weight of an oil which is normally liquid at room temperature which may be light mineral oil or a natural oil;

(b) from about 7% up to 40% by weight of a long chain polyamide having a molecular weight of between 6,000 and 9,000 and a softening point within the range of 185° C.-198° C.; and

(c) from about 7% up to about 30% by weight of an alcohol which may be a C₈ -C₁₂ primary alcohol.

At column 3, line 56 of U.S. Pat. No. 3,645,705 it is disclosed that an odor masking agent may be incorporated into the candle composition. Generally this disclosure is set forth at lines 30-44 of U.S. Pat. No. 3,645,705 thusly: "The inclusion in the composition of certain alcohols that produce otherwise desirable properties may result in a material that burns with an acrid or pungent odor. In such cases a small amount of an odor masking agent can be incorporated in the composition. The material sold by Fritzche, Dodge and Olcott as its 41984 has been found to have satisfactory results. If desired, a small amount of perfume can be added to the composition to complete the odor-masking effect."

Nothing in U.S. Pat. No. 3,645,705, however, discloses the applicability to the composition disclosed therein of insect repellent materials Nothing discloses the use of a composition of matter in U.S. Pat. No. 3,645,705 which will be both a perfumant and an insect repellent.

U.S. Pat. No. 4,051,159 issued on Sep. 27, 1977 discloses a "shaped, self-supporting transparent fragrance emitting article comprising a high percentage of a thermoplastic polyamide resin having a substantially uniformly dispersed therein a C₁₄ -C₂₂ alkyl alcohol and a fragrance emitting material" U.S. Pat. No. 4,051,159 however, does not indicate that the compositions of matter disclosed therein are useful for fragrance candles or insect repellent Indeed, much of the literature teaches away from our invention as exemplied in "Materials Tested as Insect Attractants" compiled by M. Beroza and N. Green in Agriculture Handbook No. 239 in Table 2 wherein it is stated that certain methyl substituted octenals, Items Nos. 2891, 2892, 2893, 2894 and 295 to wit:

Item 2891--2,6-dimethyl-4-octen-3-ol

Item 2892--3,6-dimethyl-5-octen-3-ol

Item 2893--3-7-dimethyl-6-octen-3-ol

Item 2894--3,7-dimethyl-6-octen-2-ol

Item 2895--3,7-dimethyl-6-octen-3-ol have attractancies for insects as follows:

Item 2891--2,6-dimethyl-4-octen-3-ol: the Oriental Fruit Fly at a level of "1" on a scale of 1-3; the Mediterranean Fruit Fly at a level of "2" on a scale of 1-3 and the Mexican Fruit Fly at a level of "1" on a scale of 1-3.

Item 2892--3,6-dimethyl-5-octen-3-ol: the Oriental Fruit Fly at a level of "1" on a scale of 1--3 and Mediterranean Fruit Fly at a level of "2" on a scale of 1-3.

Item 2893--3,7-dimethyl-6-octen-1-ol: the Oriental Fruit Fly at a level of "1" on a scale of 1--3; the Mediterranean Fruit Fly at a level of "1" on a scale of 1-3; the Mexican Fruit Fly at a level of "1" on a scale of 1--3; the Gypsy Moth on a level of "1" on a scale of 1--3; the European Chafer at a level of "1" on a scale of 1-3 and the Pink Bull Worm at a level of "1" on a scale of 1-3.

Item 2894--3,7-dimethyl-6-octen-2-ol: the Meditteranean Fruit Fly at a level of "1" on a scale of 1-3; the Mexican Fruit Fly at a level of "1" on a scale of 1-3; the Gypsy Moth at a level of "1" on a scale of 1-3; the Pink Bull Worm at a level of "1" on a scale of 1-3 and the Bolweevil at level of "1" on a scale of 1-3.

Item 2895--3,7-dimethyl-6-octen-3-ol: the Oriental Fruit Fly at a level of "1" on a scale of 1-3; the Mediterranean Fruit Fly at a level of "3" on a scale of 1-3; the Mexican Fruit Fly at a level of "1" on a scale of 1-3; the Pink Bull Worm at a level of "1" on a scale of 1-3 and the Bolweevil at a level of "1" on scale of 1-3.

Furthermore, in Agriculture Handbook No. 239 it is stated that 3-methyl-1-nonen-3-ol has on a scale of 1-3 an attractancy of "1" for the Oriental Fruit Fly and an attractancy of "1" for the Mediterranean Fruit Fly and 4,8-dimethyl-7-nonen-4-ol has on a scale of 1 to 3 an attractancy "2" for the Oriental Fruit Fly and an attractancy of "3" for the Mediterranean Fruit Fly and an attractancy of "1" for the Mexican Fruit Fly and an attractancy of "1" for Drosophila.

With respect to any of the octenol or nonenol derivatives set forth therein the USDA Agriculture Handbook No.239 indicates that the octenol and nonenol derivatives are neither attractants nor repellents for house flies (that is, Musca domestica L.).

Furthermore the U.S.D.A. Agriculture Handbook No.239 states no information pertaining to mosquitoess (e.g. Aedes aegyptae).

With respect to undecyl alcohol acetate ester, Beroza, Agriculture Handbook No.239 discloses as Item 376 the said undecyl ester of acidic acid and indicates that the Oriental Fruit Fly is attracted at a level of "1" on a scale of 1 to 3 and the Gypsy Moth is attracted at a level of "1" on a scale of 1 to 3.

Wilson, et al., U.S. Pat. No. 4,801,446 issued on Jan. 31, 1989 describes the uses of methyl-isoeugenol having the structure: ##STR2## n-dodecanol having the structure: ##STR3## and 1-(2-butenoyl(-2,6,6-trimethyl-1,3-cyclohexadiene having the structure: ##STR4## taken alone or taken in combination as attractants for house flies (Musca domestica L.(Diptera:muscidae)) and stored products moths. The structure of 1-(2-butenoyl)-2,6,6-trimethyl-1, 3-cyclohexadiene is different from the structures of any of the ketones useful in the instant invenhtion which in any event are repellents rather than attractants.

With reference to that aspect of our invention concerning insect repellent soap compositions, U.S. Pat. No. 4,707,496 issued on Nov. 17, 1987 relates to a topical insect repellent soap composition and to a method of protection using such composition Generally, the insect repellent soap composition of U.S. Pat. No. 4,707,496 comprises:

(1) from 63.0 to 99.5% by weight of a soap mixture containing from 4.1 to 7% by weight of a soap of caprylic acid, from 3.8 to 7% of a soap of capric acid, from 32.1 to 45% of a soap of lauric acid, from 12 to 17.5% by weight of a soap of myristic acid, from 5.0 to 10% by weight of a soap of palmitic acid, from 1.6 to 3% by weight of a soap of stearic acid, from 3.5 to 5% by weight of a soap of oleic acid and from 0.9 to 5% by weight of a soap of linoleic acid;

(2) from 0.1 to 2% by weight of one or more C₈ -C₁₈ straight chain fatty acids;

(3) from 0.2 to 30% by weight of a repellent chemical; and

(4) from 0.2 to 5% by weight of an effective residual insecticide.

The aroma of the caprylic acids disclosed in U.S. Pat. No. 4,707,496 cannot be considered to be asethetically pleasing and the efficacy in repelling house flies Musca domestica L.(Diptera:Muscidae)) of these caprylic acids and the efficacy of repelling mosquitoess (Aedes aegyptae) of these caprylic acids is relatively low compared with the efficacy in repelling such insects of the ketones, ketoesters and alcohols of our invention.

Thus, the instant invention applies to uses of HEDION® (trademark of Firmenich, et Cie of Geneva, Switzerland) and/or KHARISMAL™ and/or methyl jasmonate and/or alpha damascone and/or beta damascone and/or trans, trans-delta-damascone (having the structure: ##STR24## and/or 1-octen-4-ol having the structure: as repellents against house flies (Musca domestic L.(Diptera:Muscidea)) and/or mosquitoes (Aedes aegyptae).

Our invention also relates to the use of secondary undecyl acetate having the structure: ##STR25## as an attractant for Aedes aegyptae or Musca domestica L.(Diptera:Muscidae) for the purposes of utilization in insect traps and the like.

Our invention is also related to the use of the foregoing insect repellent compositions in personal soap compositions, for example, the insect repellent soap composition described in U.S. Pat. No. 4,707,496 issued on Nov. 17, 1987, the specification for which is incorporated by reference herein. Thus, in applying the teachings of U.S. Pat. No. 4,707,496 to our invention, a topical insect repellent soap composition and a method of protection using such a composition is described where the insect repellent soap composition comprises:

(i) from 63.0 up to 99.5% by weight of a soap mixture containing from 4.1 to 7% by weight of a soap of caprylic acid, from 3.8 to 7% of a soap of capric acid, from 32.1 to 45% of a soap of lauric acid, from 12 to 17.5% by weight of a soap of myristic acid, from 5.0 up to 10% by weight of a soap of palmitic acid, from 1.6 to 3% by weight of a soap of stearic acid, from 3.5 to 5% by weight of a soap of oleic acid and from 0.9 to 5% by weight of a soap of linoleic acid;

(ii) from 0.1 up to 2% by weight of C₈ -C₁₈ straight chain fatty acids;

(iii) from 10 up to 30% by weight of at least one of the repellent chemicals of our invention, e.g., one of ketoesters, ketones or alcohols set forth supra, and

(iv) from 0.2 up to 5% by weight of an effective residual insecticide as described in U.S. Pat. No. 4,707,496.

Other insect repellent soaps can be produced by adding one or more of the ketoesters, ketones and/or alcohols of our invention to one or more of the compositions described and claimed in U.S. Pat. No. 4,453,909 issued on Jun. 12, 1984 and U.S. Pat. No. 4,438,010 the specifications for which are incorporated by reference herein. Described in said U.S. Pat. No. 4,453,909 and U.S. Pat. No. 4,438,010 is a process for making a tablet of soap containing a perfume containing core, hollow, or solid fabricated from a hard plastic material either thermosetting or thermoplastic. The soap from the resulting composite tablet is useable until the core is washed clean and contains functional ingredients, e.g., the repellents described, supra and optionally aromatizing agent until the core is washed clean. This obviates the wastage of soap which normally occurs as a conventional soap tablet becomes very thin on use and at the same time gives rise to a continuously functional ingredient-containing soap, (e.g., repellent and optionally aromatizing agent) tablet. Thus, this invention also relates to detergent bars having a plastic core containing one or more of the above described ketones, ketoesters and/or alcohols and optionally a perfume. More particularly, this invention relates to detergent bars intended for conventional toilet soap uses either as hand soaps or bath or shower soaps which are elastic or inelastic in nature but which contain a solid plastic core containing insect repellent and optionally perfume giving them unique properties which alleviate wastage thereof and causes the environment surrounding the soap on use thereof to be both insect repellent and optionally aromatized in an aesthetically pleasing manner.

Yet another aspect of our invention relates to the use of the aforementioned repellents, the ketoesters, ketones and alcohols of our invention taken further in combination with N-(metal toluyl)-methyl piperidines defined according to the structure: ##STR26## as described in U.S. Pat. No. 3,463,855 issued on Aug. 26, 1969, the specification for which is incorporated by reference herein. The compounds defined according to the structure: ##STR27## include: N-(meta-toluyl)-2-methylpiperidine,

N-(meta-toluyl)-3-methylpiperidine, and

N-(meta-toluyl)-4-methylpiperidine,

The proportions of compounds defined according to the structure: ##STR28## to one or a combination of any of the ketones, ketoesters or alcohol described supra are between about 1 part N-(metatoluyl) methylpiperidine:99 parts ketone, ketoester or alcohols of our invention down to 99 parts ketone, ketoester or alcohols of our invention:1 part N-(meta-toluyl)-methyl piperidines.

In addition, the compositions useful in repelling insects of our invention can also contain 1-nonen-3-ol described and claimed in U.S. Pat. Nos. 4,693,890 and 4,759,228 issued on Jul. 26, 1988, the specifications for which are incorporated by reference herein. The ratio of 1-nonen-3-ol:ketone, ketoester or alcohols of our invention useful in repellent compositions may vary from about 1 part 1-nonen-3-ol:99 parts ketone, ketoester or alcohols of our invention down to 99 parts 1-nonen-3-ol:1 part ketone, ketoester or alcohols of our invention.

Our invention also relates to apparatus useful in determining the attractancy of such molecules, including, but not limited to said ester having the structure: ##STR29## and the repellency against insects of the ketones, ketoesters and alcohols described supra against insects to wit Musca domestica L.(Diptera:Muscidae) and mosquitoes (Aedes agyptae) and processes for using such apparatus which apparatus comprises:

(i) active and passive insect interest electronic, detecting, measuring and recording means collectively denoted as "DMR" means which is connected to an electronic power source, comprising detecting means, measuring means and recording means;

(ii) enclosed insect feeding and/or stimulating means, collectively denoted as "IFS" means, having control limited access to the external environment surrounding said apparatus and associated with the said "DMR" means and including said detecting means, said "IFS" means being located at a fixed "IFS" means location defined according to "X", "Y" and "Z" coordinates having a defined first 3-space, said "IFS" means consisting essentially of:

(a) a substantially, horizontally-positioned insect feeding and/or stimulating microporous substantially planar lamina which is a porous membrane having and upper outer surface and a lower inner surface, said lamina being located immediately above said enclosed "IFS" means;

(b) an insect attractant quantitative detecting means located immediately below said lamina and within said enclosed "IFS" means comprising at least 2-spaced electrically conductive elements;

(1) connected to said "DMR" means; and

(2) capable of forming a complete circuit, said elements having such dimensions and spacing from one another as to cause an attracted insect to complete a circuit of electron flow through or proximate to said elements;

(c) located on said upper outer surface of said lamina a feeding stimulate composition or stimulate composition for insects (for example, agar);

(iii) steady state infra red, ultra voilet and/or visable monochromatic or polychromatic radiation means for supplying at least one beam of radiation (ultra violet, infra red and/or visable light) having a given substantially constant intensity or intensities and wave length or wave lengths to said "IFS" means location said beam(s) of radiation being directed in a direction perpendicular to the plane of said lamina along a directional vector from above or below said insect attractant quantitative detecting means; and

(iv) steady state air and treatment (experimental or actual) supply and conduction means denoted as "SAC" means for supplying and conducting air and treatment agent (experimental or actual) at a substantially constant flow rate and substantially constant linear velocity into said defined 3-space at least initially along a vector in a direction substantially parallel to the plane of said lamina at a location below said lamina simultaneously with the supplying of the beam(s) of radiation to said "IFS" means location

said insect feeding and/or stimulating lamina being constructed and said detecting means being constructed so that said "DMR" means are sensitive to the completion of a circuit of electron flow through or proximate said conductive elements of said insect attractant quantitative detecting means whereby the number and frequency of the insects attracted relative to the attractancy of said radiation means to the proximity of said "IFS" means is capable of being determined using said "DMR" means.

Thus, the air and treatment agent enters the apparatus at one or a plurality of side portals (e.g., as many as ten portals) substantially perpendicular to the vertical side wall of the apparatus. The treatment agent may either (i) be premixed in the gas phase (using appropriate temperature and pressure conditions) with the air at a designated premixed location or (ii) be located in a control release system (CRS™) mode in, for example, a solid (e.g. organic polymeric or inorganic (e.g. silica) matrix partially obstructing the air flow whereby the air screen inpinges upon a treatment agent-containing solid state matrix and the air stream extracts treatment agent molecules from the matrix into the air stream Such solid polymers containing functional ingredients may be prepared, for example, according to the disclosure of U.S. Pat. No. 4,543,367 issued on Sep. 24, 1985 or U.S. Pat. No. 4,521,541, the specification for which is incorporated by reference herein. Thus, a process can be used for preparing extruded repellent-containing thermoplastic foamed particles using chemical blowing agents or direct gas extrusion processes. The process described in U.S. Pat. Nos. 4,543,367 and 4,521,541 involves the use of a single screw or double screw extruder wherein the resin particles are added upstream from the repellent fluid or solid which is in turn added to the extruder upstream from the point of addition of the liquid or gaseous blowing agent.

The resulting air-treatment agent gaseous stream then feeds into the enclosed "IFS" means either (i) parallel to the microporous planar lamina or (ii) is rotated (using appropriately designed fluid flow apparatus sections such as a tube elbow) about 90° and this flows substantially perpendicular to the microporous planar lamina.

Thus, in testing the insect repellency or attractancy of such molecules as the ketones, ketoesters, alcohols or esters of our invention, the apparatus set forth supra may be used or a second testing technique may be used which concerns the electrophysiological study of the neural corrolates of attraction and repulsion in Musca domestica L.(Diptera:Muscidae) (house flies). Different points in the house fly olfactory neuroarchitecture were studied using electrophysiology in an effort to identify the neural corrolates of attractant and repellent signals resulting from potentially attractant and repellent substances.

Recordings from the antennal lobe of the deuterocerebrum of the Musca domestica L.(Diptera:Muscidae) showed that the repellent signals were highly distinguishable from the attractant signals. Signals from repellents (e.g., alpha damascone, beta damascone, trans, trans-delta-damascone and the like) showed a shift in base line potential of approximately 25 m volts whereas attractant signals showed no shift.

Thus, neural signals of the antennal lobe are used herein as an assay for olfactory canvassing to predict behavioral activity of the Musca domestica L.(Diptera:Muscidae) (house flies).

By the same token, neural signals of the antennal base, the funiculus and the antennal nerve can be used herein as an assay for olfactory canvassing to predict behavioral activity of the Musca domestica L.(Diptera:Muscidae) (house flies). In addition to the soap fabrication, another aspect of our invention relates to the formation of repelling articles containing one or more of the ketones, ketoesters or alcohols, that is, articles useful for the repelling of house flies Musca domestica L.(Diptera:Muscidae)) or mosquitoes (Aedes agyptae) in combination with compatible polymers (e.g., high density polyethylene or low density polyethylene). Thus, another aspect of our invention provides a process for forming ketones, ketoester or alcohol-containing polymeric particles such as foamed polymeric pellets which include a relatively high concentration of ketones, ketoesters or alcohols of our invention as defined supra.

Thus, another aspect of our invention relates to the formation of ketone, ketoester or alcohol polymeric pellets by means of introduction into a single screw or twin screw extruder of in series from a plastic polymer followed by ketones, ketoesters or alcohols of our invention which is compatible with the thermoplastic polymer, in turn, (optionally) followed by introduction of gaseous blowing agent or blowing agent which will produce a gas which is inert to the polymer and to the ketones, ketoesters or alcohols previously introduced into the extruder

The advantages of using a foamed polymeric particle are multiple to wit:

improved handling, greater retention of the ketones, ketoesters or alcohols when not in use;

greater length of time during which the release of the ketones, ketoesters or alcohols of our invention from the polymer is at "steady state" or "0 order"

The nature of the extruder utilized in the process of our invention to form the polymeric ketones, ketoesters or alcohol-containing polymer particles for our invention may be either single screw or double screw. Thus, the types of extruder that can be used are disclosed at pages 246-267 and 332-349 of the Modern Plastics Encyclopedia, 1982-1983, published by McGraw-Hill Publishing Company, the disclosure of which is incorporated by reference herein. More specifically, examples of extruders which are usable in carrying out one of the processes of our invention (with modification for introduction of at least one of the ketones, ketoesters or alcohols of our invention) downstream from the introduction of the polymer and with further modification that the gaseous blowing agent is introduced still further downstream from the point of introduction of the ketones, ketoesters or alcohols of our invention are as follows:

9. The Berstorff single screw, twin screw, or foam extrusion equipment manufactured by Berstorff Corporation, P.0. Box 240357, 8200-A Arrowridge Blvd., Charlotte, N.C. 28224.

In producting the ketone, ketoester or alcohol-containing polymer particles of our invention various polymers may be utilized, for example, low density polyethylene high density polyethylene, polypropylene, the co-polymer of ethylene and vinyl acetate, and polyvinyl chloride More specifically, the polymers used in the practice of our invention may be co-polymers of ethylene and a polar vinyl monomer selected from (a) vinyl acetate; (b) ethyl acrylate; (c) methyl acrylate; (d) butyl acrylate and (e) acrylic acid including the hydrolyzed co-polymer of ehtylene and vinyl acetate Preferred co-polymers are ehtylene vinyl acetate with about 9 to 60% vinyl acetate and ethylene-ethyl acrylate with about 6 to 18% ethyl acrylate.

Resins of the type disclosed for use as co-polymers are commercially available in the molding powder form. For example, ethylene vinyl acetate co-polymers are markete the E. I. duPont Nemours Company under the tradename "ELVAX®" and by Arco Polymer Division under the trademark "DYLAND®" and by the Exxon Corporation of Linden, N.J. under the trademark "DEXXON®". Ethylene/ethyl acrylate co-polymers are marketed by Union Carbide Corporation under the trademark "EEA RESIN®".

The polymer is added to the single screw or twin screw extruder at a feed rate in the range of from abut 80 up to about 300 pounds per hour while maintaining the temperature of the screw extruder between about 160° and about 240° C. If the polymer or co-polymer powder is added to the extruder at a reference "barrel segment", then the ketones, ketoesters or alcohols of our invention is added to the extruder under pressure downstream from the retention point of the polymer of one or more of "barrel segments" (S-2, S-3, S-5, S-6, S-7, S-8, or S-9) (referring to FIG. 37 briefly described, supra and described in detail infra).

The proportion of ketones, ketoesters and/or alcohols (taken further together with other insect repelling materials) to resin can vary from small but effective amounts on the order of about 1% of the weight of resin body up to about 45% by weight of the resin body In general, it is preferred to use between about 5% up to about 30% based on the weight of the resin body of insect repellent composition of our invention. This is an optimum amount balancing the proportion of insect repellent composition of our invention against the time period over which the article emits the insect repellent composition and against the tendency of the components of the insect repellent composition to oil out either individually or in combination This "oiling out" is specifically avoided as a result of the use of the foaming agent discussed infra.

Downstream from the addition point of the ketones, ketoesters or alcohols taken together with other insect repellent agents, optionally, the gaseous or liquid containing blowing agent may be added (e.g. at "barrel segments" (S-5, S-6, S-7, S-8, S-9 or S-10) using the polymer addition "barrel segment" as a reference "barrel segment" S-1. Examples of gaseous blowing agents are carbon dioxide, nitrogen, mixtures of nitrogen and carbon dioxide in proportions of from 1 up to 99% by volume nitrogen and 99 down to 1% by volume carbon dioxide, helium, mixtures of helium and nitrogen, mixtures of helium and carbon dioxide and other gases which are inert at the temperature and pressure of the polymer at the time of the extrusion operation. Thus, gas containing oxygen or other reactive gases, e.g., hydrogen, should be avoided. The pressure of the gas blowing agent being added to the extruder at the point of addition may vary from about 80 up to about 150 psig. Higher pressures may be used without adversely affecting the usefulness of the foamed insect repellent composition-containing particle.

The feed rate range of insect repellent composition-containing but not limited to the ketones, ketoesters or alcohols of our invention, may be between about 0.5% up to about 45% by weight of the polymer.

The die of the extruder may create rod, sheet, film or ribbon. The resulting product may then, if desired, be pelletized to form insect repellent composition-containing polymer particles or the ribbon may be used "as is" as an insect repellent-containing polymeric article of manufacture itself.

In addition to the optional gaseous blowing agents (which are necessarily "inert" gases), blowing agents may be added at the same point on the extruder which will create gaseous voids in the insect repellent-containing polymer articles of our invention and these "blowing agents" are well known to one having ordinary skill in the art. Examples of such non-gaseous containing materials which yield gases on admixture with the polymer in the extruder but which are still inert to the insect repellent (or attractant as the case may be) are as follows:

(i) Under high pressure, ethylene, methane, propane, butane, propylene, methyl chloride, methyl bromide, vinyl chloride and methylene dichloride as more specifically described in U.S. Pat. No. 2,387,730, the specification for which is incorporated by reference herein;

No. 3,298,975 issued on Jan. 17, 1967, the specification for which is incorporated by reference herein.

The resulting extruded (and if desired pelletized) material may then be, for example, injection molded to form a useful article Such injection molding can be carried out in accordance with the procedure as set forth in U.S. Pat. No. 3,268,636 issued on Aug. 23, 1966, the specification for which is incorporated by reference herein.

In addition, our invention relates to candle body materials which on use are both insect repellent and perfuming which contain one or more of the ketones, ketoesters and/or alcohols and other insect repellent materials including at least one of the compounds having the structure: ##STR30## in order to repel house flies (Musca domestica L.(Diptera:Muscidae)) and/or mosquitoes (Aedes agyptae)

The house fly and mosquito-repellent-perfuming compositions which form part of the candle body materials are within the following specifications:

(I) from 5 up to 100% by weight of an efficacious perfuming/insect repellent composition containing at least one of the ketones, ketoesters and/or alcohols (II) from 0 up to 95% by weight of a standard perfuming substance (non-insect repellent or insect repellent) which may be one or a combination of the following materials:

the methyl ester of 2,5-dihydroxy- 4,6-dimethyl benzoic acid;

dihydro myrcenol;

oakmoss absolute;

benzyl acetate;

geraniol;

isobornyl acetate;

citronellyl acetate;

para-t-butyl phenyl isovaleraldehyde;

benzyl salicylate;

hexyl cinnamic aldehyde;

geranonitrile;

patchouli oil;

alpha-terpineol;

tetrahydromuguol;

phenyl ethyl alcohol;

cedrenal;

methyl ionone;

cinnamyl acetate;

benyzl benzoate;

L-Citronellal;

nerol;

geranyl formate;

geranyl acetate;

eugenol;

alpha Farnesene;

beta Farnesene;

citral;

n-Nonanal; and

n-Octanal

The foregoing formula may require a solubilizing agent, e.g., the metyl ester of dihydroabietic acid (commercial name: HERCOLYN D®, benzyl benzoate, isopropyl myristate and/or C₁₂ -C₁₄ isoparaffin hydrocarbons.

The candle base composition can be standard paraffin wax, or it can be transparent or pastel shaded as more particularly described in U.S. Pat. No. 3,615,289 issued on Oct. 26, 1971 (the disclosure of which is incorporated by reference herein) and wherein the candle body comprises as the basic components a mixture of:

(i) a thermoplastic polyamide resin formed from linoleic acid polymerized with a polyamine compound;

(ii) an alkanol amide or alkanol amine; and

(iii) a stearic acid compound.

The weight ratio of candle body:insect repellent/ perfumant substance of our invention may vary from about 0.8% up to about 10% with a range of from about 0.8% up to about 10% with a range of from about 0.8% up to about 2.0% being preferred when no non-insect repelling perfume oil is used in conjunction with the ketones, ketoesters and/or alcohols of our invention; and with a range of from about 1.5% up to about 10% by weight of the overall composition being preferred when a non-insect repelling perfume oil is used in conjunction with the ketones, ketesters and/or alcohols of our invention.

Specifically, the polyamide may be a "VERSAMID" resin which is a thermoplastic condensation product of polymerized linoleic acid with various polyamine compounds such as ethylene diamine, ethylene triamine and the like. "VERSAMID" compounds are VERSAMIDE® 900", "VERSAMIDE® 930", "VERSAMID® 940", "VERSAMID® 1635". These compounds are products of the Henkel Chemical Corporation of Minneapolis, Minn.

Another substance required in the clear candle composition consists of about 20-55% by weight of an alkanol amine or alkanol amide prepared by the reaction of a fatty acid ester and amine whereby the ester and the amine are in substan equal proportions, for example, compounds such as BARLOL® 12C2 (manufactured by the Barrid Chemical Company) a monoalkyl diethanolamine have 8 to 18% carbon atoms in the alkyl chain. A third component of the clear plastic candle composition comprises one or more stearic acid esters or a mixture of stearic acid esters and stearic acid. These esters include such compounds as isopropyl isostearate, butyl stearate and hexadecyl stearate. These stearic acid compounds serve as stabilizing agents which permit the ready incorporation of the insect repellent/perfumant compositions of our invention up to a level of approximately 5% (total proportion of perfume oil-insect repellent composition). They are carriers for the perfumant/insect repellent and may be used in a proportion of between 1 and 50% by weight of the composition although the preferable range is betwen 20 to 30%. In this connection it is possible to use up to about 10% by weight of a perfumant/insect repellent if part of the formula is replaced by the material "NEVEX®100", a product which is a coumarin-indene copolymer resin of very little unsaturation manufactured by the Neville Chemical Company.

Rather than being a crystalline paraffin wax the candle base of our invention may be an oil gel that has as its base a light mineral oil, an inexpensive natural oil or a combination of such oils which oil gel has a non-greasy surface and feel and sufficient rigidity to be self-supporting at room temperatures. Such a gel is disclosed in U.S. Pat. No. 3,645,705 issued on Feb. 29, 1972, the disclosure of which is incorporated by reference herein. Such compositions of matter include:

(a) from about 35% up to about 85% by weight of an oil which is normally liquid at room temperature chosen from the group consisting of light mineral oils and natural oils having iodine values substantially within the range of 40-135;

(b) from about 7% up to about 40% by weight of a long chain polyamide having a molecular weight substantially within the range of 6000-9000 and a softening point substantially within the range of 18° C.-48° C.; and

(c) from about 7% up to about 30% of an alcohol selected from the group consisting of 8 to 12 carbon primary alcohols.

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 is an exploded view of an olfactometer apparatus of the prior art, U.S. Pat. No. 4,759,228 issued on Jul. 26, 1988, the specification for which is incorporated by reference herein used in testing the efficacy of, for example, alpha damascone, beta damascone, delta damas trans, trans-delta-damascone, methyl jasmonate, HEDION® and KHARISMAL™ as house fly (Musca domestica L. (Diptera:Muscidae)) and mosquito (Aedes aegyptae) repelling materials and used in testing 2-undecyl acetate as a house fly or mosquito attracting material. Air source 634 feeds air through line 635 through air distributors 636, 636a, et seq. onto base plate 617 containing insect landing sites 610, 610a, et seq. The base plate 617 is separated from the spacer plate 629 for the air lines 636 whereby the air lines 636 are held in place at positions 631, 631a, et seq. using spacer ring 628. Air exits through line 633a using exhaust fan 633.

Such compositions may additionally include from about 1% up to about 15% of a methyl ester; up to about 5% by weight of stearic acid and up to about 5% by weight of an oxidation inhibiting agent and up to about 5% by weight of an acid selected from the group consisting of dimer and trimer acids.

Simultaneously with the supplying of air from air source 634, light is supplied through light guides 652, 652a, et seq. from light source 651 which is powered by electric power supply 650. An example of such light guide is marketed by RADIO SHACK® Division of Tandy Cor of Fort Worth, Tex. 76102 under the trademark ARCHER®, Catalog No. 276-228 ("1.0 mm optical plastic fiber length 5 meters"). An example of light source 651 is KRATOS Monochromatic Illuminator GM 100 Miniture VIS-IR Grating Monochromator (Model No. GM 100-1, GM 100-2, GM 100-3 or GM 100-4) as manufactured by KRATOS Analytical Instruments Corporation, 170 Williams Drive, Ramsey, N.J. 07446. Another light supply source is the KRATOS GM 200 Double Grating Monochromator. Another example of a useful light source is the KRATOS GM 252 High Intensity Grating Monochromator.

The olfactometer of the prior art of FIG. 1 is assisted with computer apparatus shown in schematic form and block flow 639. Dampers 611a, 611b, et seq. hold base plate 617 in place horizontally. When an insect lands on landing sites 610, 610a, et seq., the landing is recorded electrically through a sensor. The sensor which is, in fact, a transducer causes an electrical impulse caused by the pressure of the insects landing to proceed through wire 619 (held in position by holder 612) to a multi-channel A.C. converter 623 (using electric power supply 639). Converter 623 is associated with programmed tape storage 624, printer 620 and data link to digital computer 621. Thus, a recording of the data as set forth in Tables I, II, et seq., supra is effected.

FIG. 1-A is an exploded view of a first embodiment of the olfactometer apparatus of our invention used in testing, inter alia, the efficacy of, for example, trans, trans-delta-damascone as a house fly (Musca domestica L.(Diptera: Muscidae)) or mosquito (Aedes agyptae) repelling material or 2-undecyl acetate as a house fly or mosquito attracting material. Their supply source 2634 feeds air through line 2634a to mixing station 2636. Treatment agent from source 2635 (e.g., such as the alpha-damascone, beta-damascone, trans, trans-delta damascone, methyl jasmonate or KHARISMALTM™ to be tested as a house fly or mosquito repellent agent) is fed through line 2635a to mixing station 2636. At mixing station 2636, the air is mixed with the treatment agent such as the trans, trans-delta-damascone. The resulting air-treatment agent mixture (in the gas phase) is fed through a plurality (if desired) of lines e.g., 2636a and 2636g into portals at the side of the apparatus along a directional vector parallels to the surface of base plate 2625 just above said base plate 2625 and just below insect attractant quantitative detecting means grids 2610. The base plate 2625 is separated from the spacer plate 2629 whereby the air-treatment agent lines 2636a, 2636g, et seq are held in place using spacer ring 2628. Air and treatment agent in the gas phase exits through line 2633a using exhaust fan 2633 to the environment 2537.

The air exit is indicated by reference numeral 2537.

Simultaneously with the supplying of air and treatment agent from air supply source 2634 and treatment agent source 2635, light is supplied from above the enclosed insect feeding and/or stimulating means (collectively denoted as "IFS" means through light guides 2652 from light source 2551 which is powered by electric power supply 2550. An example of such light guide is marketed by RADIO SHACK® division of TANDY Corporation of Fort Worth, Tex. 76102 under the trademark ARCHER®, Catalog No. 276-228 ("1.0 mm optical plastic fiber length 5 meters"). An example of light source 2551 is KRATOS Monochromatic Illuminator GM 100 Miniture VIS-IR Grating Monochromator (Model No. GM 100-1, GM 100-2, GM 100-3 or GM 100-4) as manufactured by KRATOS Analytical Instruments Corporation, 170 Williams Drive, Ramsey, N.J. 07446. Another light supply source is the KRATOS GM 200 Double Grating Monochromator. Another example of a useful light source is the KRATOS GM 252 High Intensity Grating Monochromator.

The base plate 2625 is also separated from the spacer plate 2629 for the light guides 2652 whereby the light guides 2652 are held in place. In the first embodiment illustrated in FIG. 1-A as well as in partial views in FIGS. 1-B, 1-C, 1-D, 1-E and 1-Da, spacer ring 2628 separates plate 2629 which holds the light guides 2652 in place from plate 2625 on which landing pads 2680 are located (shown in FIG. 1-C).

The olfactometer of FIG. 1-A is assisted with computer apparatus shown in schematic form and block flow diagram using reference numerals 2520, 2521, 2523, 2524 and 2529. Dampers 2611 hold base plate 2625 in place horizontally When an insect lands on landing site 2680, the landing is recorded electrically through a sensor 2610 shown in magnified form in FIG. 1-F. The sensor causes an electrical impluse caused by the pressure of the insects landing to proceed through wire 2619a, 2619b, et seq. (held in position by holder) 2512) to a multi channel A.C converter 2523 (using electric power supply 2539). Converter 2523 is associated with program tape storage 2524, printer 2520 and data link to digital computer 2521 Thus, a recording of the data as set forth in Tables I, II, et seq., supra is effected.

FIG. 1-B is a top view looking down at spacer plate 2629 of the apparatus of FIG. 1-A showing the locations of the entry of the light guides 2652 above the sensors 2610 and showing the entry of the air and treatment agent mixture (from mixing station 2636) into portals along a directional vector parallel to the surface of plate 2629 and immediately beneath the sensors 2610.

FIG. 1-C sets forth in detail a partial cross section view of the base section of the apparatus of FIG. 1-A indicating the location of insect landing pad 2680 just below the electrical sensor 2610 and showing the electrical sensor 2610 below the light guide 2652 for provision of mono and/or polychromatic radiation in a direction along a directional vector perpendicular to the plane of the electrical sensor 2610.

FIGS. 1-D, 1-E, 1-F show detail views of (i) the active and passive insect interest electronic detecting means (collectively denoted as "DMR" means) and (ii) the enclosed insect feeding and/or stimulating means collectively denoted as "IFS" means having control limited access to the external environment surrounding the apparatus and associated with the "DMR" means.

The insect feeding and/or stimulating means consists of:

(a) a substantially, horizontally positioned insect feeding and/or stimulating microporous substantially planar lamina 2662 which is a porous membrane having an upper outer surface and a lower inner surface with the lower inner surface of element 2662 parallel to the surface of the sensor 2610 which is parallel to the plane of the insect landing pad 2680 and also parallel to the flow of the air-treatment agent stream emanating from flow line 2636g (referring to FIG. 1-D). Thus, the insect attractant quantitative detecting means which is located immediately below the lamina 2662 and within the enclosed "IFS" means consists of the electrically conductive elements shown using reference numeral 2610 held by holders 2610a and 2610b and connected to the "DMR" means using wires 2619a and 2619b. Also connected to the "DMR" means is the sensing electrode 2679 (shown in FIG. 1-F) immersed in the insect feeding and/or stimulating composition 2664 (e.g., agar) contained in container 2660 with the inner void thereof, being indicated by reference numeral 2660a (shown in FIGS. 1-D, 1-E and 1-F). Each member of the grid of the sensing element 2610 is shown using reference numerals 2699. In another embodiment shown in FIG. 1-Da the sensing element 2610 rather than being held on plate 2625 is hung from spacer plate 2629 using holders 2671a and

2671b as shown in FIG. 1-Da. The sensing section 2610 is still maintained in fixed position immediately below microporous lamina 2662 and immediately above insect landing site 2680 which is located in fixed position on plate 2625.

In another embodiment, in FIG. 1-G, the treatment agent is fed through portal 2648 from line 2636g and is then rotated past location 2646 through grid 2649 via orifices 2647 in a direction along a directional vector perpendicular to the plane of the electrical sensor 2610 and perpendicular to the plane of the sensor wires 2699 which are held in place by holders 2610a and 2610b.

FIG. 1-H sets forth in perspective an exploded view of a second embodiment of the olfactometer apparatus of our invention used in testing the efficacy of, for example, the alpha-damascone, beta-damascone, trans, trans-delta-damascone, methyl jasmonate and KHARISMAL™ of our invention as house fly (Musca domestica L.(Diptera:Muscidae) and mosquito (Aedes agyptae) repelling materials and of, for example, 2-undecyl acetate as house fly and mosquito attracting materials.

Air supply source 3634 provides air to mixing station 3636 wherein the air is mixed with treatment agent from treatment agent source 3635 (source of, for example, alpha-damascone). The resulting mixture passes through tube 3636g (for example) and enters the apparatus through side portals. The entry is through spacer plate 3628 and above base plate 3625 The entry of the air-treatment agent is in a direction parallel to the surface of the base plate 3625. Thus, the base plate 3625 is separated from the spacer plate 3629 for the air-treatment agent (e.g., alpha-damascone) lines 3636g (shown in FIG. 1-H) and 3636a and 3636g shown in FIG. 1-L. Air exits through line 3633a using exhaust fan 3633.

The air exit is indicated by reference numeral 3537 in FIG. 1-H.

Simultaneously, with the supplying of air and treatment agent from mixing station 3636, light is supplied from beneath the enclosed insect feeding and/or stimulating means collectively denoted as "IFS" means through light guides 3652, from light source 3551 which is pow by electric power supply 3550 marketed by RADIO SHACK®, Division of Tandy Corporation of Fort Worth, Tex. 76102 under the trademark ARCHER , Catalog No. 276-228 ("1.0 mm optical plastic fiber length 5 meters"). An example of light source 3551 is KRATOS Monochromatic Illuminator GM 100 Miniture VIS-IR Grating Monochromator (Model No GM 100-1, GM 100-2, GM 100-3 or GM 100-4) as manufactured by KRATOS Analytical Instruments Corporation, 170 Williams Drive, Ramsey, N.J. 07446. Another Monochromator Another example of a useful light source is the KRATOS GM 252 High Intensity Grating Monochromator. The base plate 3625 is also separated from the spacer plate 3629 for the light guides 3652 whereby the light guides 3652 are held in place in the base plate 3625 whereby the light (or other forms of radiation) is directed in a direction perpendicular to the electrical sensor element 3610. Air supply source from location 3634 and treatment agent from location 3635 is mixed at mixing station 3636 where upon treatment agent and air in admixture is passed through lines 3636a and 3636g (shown in FIG. 1-L) through portals located in the spacer element 3628 in a direction along a directional vector parallel to the electrical sensing element 3610 held in place by holders 3610a and 3610b. The electrical sensing elements are located directly below the horizontally positioned insect feeding and/or stimulating microporous substantially planar lamina 3670 which is held in place by ring 3660 located on spacer plate 3629 spaced from the base plate 3625 by spacer ring 3628. It should be noted that the spacer plate 3629, spacer ring 3628 and base plate 3625 enclose the entire "enclosed insect feeding" and/or stimulating means collectively denoted as "IFS" means which have control limited access to the external environment surrounding the apparatus and in which the insects to be tested, e.g., mosquitoes or house flies are placed.

The insect attractant quantitative detecting means made up of wires 3699 (the entire grid being denoted using reference numeral 3610) is located immediately beneath the porous membrane 3670, the outer surface of which contains a feeding stimulant composition or stimulant composition for insects (for example, agar) indicated by reference numeral 3664 in FIG. 1-M. Immersed in the feeding stimulate composition or stimulant composition for insects (e.g., agar) is electrode 3679 connected to wire 3619 which connects with either wire 3619a or 3619b which is connected to the grid wires 3699 (which make up the insect attractant quantitative detecting means located immediately below lamina 3670).

The olfactometer embodiment of FIG. 1-H (also shown in FIGS. 1-J, 1-L and 1-La is assisted with computer apparatus shown in schematic form and block flow diagram form in FIGS. 1-H and 1-L using reference numerals 3520, 3521, 3523 and 3524 as well as 3639. Dampers 3611 hold base plate 3625 in place horizontally. When an insect lands on the grid having wires 3699, the landing is recorded electrically through a sensor shown in magnified form in FIGS. 1-O and 1-P and in addition in FIG. 1-F. The sensor causes an electrical impulse caused by the pressure of the insects landing to proceed through wires 3619a and 3619b to an electrically biased differential amplifier 3639 (using electric power supply 3539) also connected to wire 3619c which is connected to the electrode 3679 which immersed in the feeding stimulant composition or stimulant for the insect 3674, and then to a multi-channel A.C. converter 523. Converter 3523 is associated with program tape storage 524, printer 3520 and data link to digital computer 3521 A variation is shown in FIG. 1-L wherein the differential amplifier 3639 is connected in series to electrical biased for psuedo host 3669 which in turn is connected to wire 3619 which in turn is connected to the electrode 3679 immmersed in the insect stimulant composition 3674 located on the surface of porous lamina 3670.

FIGS. 1-Lb, 1-Lc, and 1-Ld show the use of the optional heating elements located in base plate 3625. Thus, FIG. 1-Lb is a cut-away side elevation schematic view of a detailed section of the olfactometer of our invention and is in fact a third embodiment of the olfactometer of our invention indicating the presence of heating coils 3662a and 3662b in base plate 3625. Air and treatment agent are fed into portals located in spacing ring 3628 while radiation is transmitted through light guides 3652 held in place on base plate 3625. Base plate 3625 is spaced at a reasonable distance (e.g., 1.0") using spacer ring 3628 which is sealed in place using silicone seals for example. The sensor 3610 is held in place also as a result of being sealed in spacer ring 3628. The sensor 3610 is also suspended in a plane immediately beneath the microporous lamina 3670 on which the insect stimulating composition is located and into which electrode 3679 (connected to wire 3619c) is placed.

Thus, in this third embodiment as shown in FIGS. 1-Lb, 1-Lc and 1-Ld, as well as for the heating coils 3662a and 3662b is contained in base plate 3625 and is indicated by reference numeral 3657. Base plate 3625 is located on a stand which is situated on dampers 3611. The top view of the olfactometer looking down on face plate 3629 is set forth in FIG. 1-Lc. The reference numeral 3629 refers to the face plate, per se. Hidden lines 3662a and 3662b are representations of the heating coils through which heat transfer fluid is supplied through lines 3662a and 3662b (with heated water) using pump 3663, the heat for which is controlled using controller 3664. Coils 3662a and 3662b are preferably covered at cavity 3657 with a heat transfer paste FIG. 1-Ld is also a top view of the olfactometer with the face plate removed looking directly down on the base plate 3625.

FIG. 1-M sets forth a partial cross-section of another embodiment of the apparatus of FIG. 1-H wherein the treatment agent (alpha-damascone, beta-damascone, and the like) is located in a microporous polymeric matrix and the particles of microporous polymer (e.g., polyethylene containing embedded therein alpha-damascone) is set forth using reference numeral 4635. Thus, the treatment agent is located in a control release system (CRS™) mode shown in particles in 4635. A mixing screen 4636 is located downstream from the polymeric treatment agent-containing matrix 4635. Air flowing through tube 3636g passes through and is resisted by the particles 4635 whereupon the air becomes entrained with treatment agent, e.g., alpha-damascone. The resulting gas mixture then is further mixed in screen 4636 and then passes in a direction along a directional vector substantially parallel to grid 3699 beneath lamina 3670 on which is located insect stimulant agent 3664 (e.g., agar). Inserted into the insect stimulant agent is electrode 3679 either diagonally or vertically through portal 4619 in element 3660. Simultaneously, radiation is emitted through radiation tube 3652 in a direction perpendicular to the flow of the air-treatment stream and in a direction perpendicular to the surface of lamina 3670 on which insect stimulant agent 3664 is located. FIGS. 1-O and 1-P set forth front views of grid 3610 which is the insect sensing device Reference numeral 3644 shows another microporous membrane. Below the microporous membrane 3644 is located the wires of the insect detecting means 3699 and on the outer surface of membrane 3644 is the insect stimulant composition (e.g., agar) indicated by reference numeral 3664. Membrane 3644 may be supported by another membrane (e.g., 3660a) or it need not be supported assuming that it is thick enough to withstand the weight of the insect stimulating composition 3664.

The slide was then placed under a dissecting microscope to enable a more accurate placement of the electrode.

Microcapillary electrodes (tip O.D. 1-5 mm) were filled with an ionic flourescent solution which served the dual purpose of a conducting solution as well as marking the recording site. The ionic solution contained Lucifer yellow CH, a super-fluorescent lithium salt of 3,6-disulphonate 4-aminonaphlthalimide (Stewart, W. W. 1978 "Functional connections between cells as revealed by dye-coupling with a highly flourescent naphthalimide tracer" Cell 14: 741-759), which is taken up by depolarizing neurons via induced endocytosis (Wilcox and Franceschini, N. 1984 "Illumination induces dye incorporation in photoreceptor cells" Science (Washington, D.C.) 225: 851-854).

The active electrode was positioned in the selected spot using Nashike micromanipulators with remote hydraulic drive. Areas for electrophysiological study were located using (Strausfeld, N.J. 1978 "Atlas of an insect brain", Springer-Verlag Berlin) (1976) detailed anatomical study of the house fly brain, which includes a three-dimensional coordinate system. Subsequent gross dissections showed that with much practice, individual lobes on the brain could be penetrated with repeatable accuracy.

The indifferent electrode was placed either in the head capsule or thorax The preferred position was the thorax as this places the electrode out of the way. However, care must be taken not to place the indifferent electrode in the ventral nerve cord as this results in extraneous nerve signals

In placing the active electrode, it was necessary to prick the cuticle with a minuten pin in order to prevent deformation of the head capsule as the electrode penetrated. This method minimized damage to the underlying neural tissue

Nerve signals were preamplified with custom neutral amplifiers at 100× and then displayed on Nicolet 3091 oscilloscope. The same signal was simultaneously sent to a Dianachart smart recorder/data logger to obtain a hard copy of the neural signal. The olfactory stimulus was initially supplied using the technique developed by Kauer, J. S.; Shepherd, G. M. 1975 "Olfactory stimulation and monitored step pulses of odor", Brain Res. 85: 108-113 and Getchel, T. V.; Shepherd, G. M. 1978 "Responses of olfactory receptor cells to step pulses of odor at different concentrations in the salamander", J. Physiol. 282: 521-540 which uses three concentric pipettes, one to apply the odor and the other two to exhaust the odor. However, this system proved to be too bulky for house flies due to their small size, as it was not possible to form three concentric pipettes which were small enough not to be bulky, but not so small as to restrict air flow.

Consequently, a system was developed which used pressurized air to deliver the odor and an exhaust system was built around the entire set up. The delivery system was a test tube containing 2 ml of odor extract, stoppered with two disposable pipettes through the rubber stopper (as is shown in FIG. 36). One pipette 104 was attached to a pressurized air tank and the other pipette 112 was attached to a tygon tube terminating in a capillary tube which could be positioned directly in front of the fly's antennae.

Odor delivery (e.g. methyl isoeugenol) was controlled with a valve 113 so that abrupt onset of the stimulus was possible. Each stimulus was approximately 4-5 seconds in duration. A minimum of 15 minutes was used between odor stimulus to allow the previous odor to be completely exhausted from the area.

FIG. 37 is a schematic cut-away elevation diagram of an extrusion and pelletizing apparatus useful in carrying out a process of our invention during the operation of said apparatus whereby the insect attractant or repellent is incorporated into a polymer such as a polyethylene. Motor 15 drives the extruder screws located at 23A in barrel 16, the extruder being operated at temperatures in the range of about 150° C. up to about 250° C. At the beginning of the barrel resin at source 12 together with additives, e.g., processing aids and densifiers at location 13 is added via addition funnel 14 into the extruder Simultaneously (when the operation reaches "steady state"), insect attractant, 2-undecyl acetate or insect repellent, e.g., alpha-damascone, beta-damascone, methyl jasmonate or any of the other ketones, ketoesters or alcohols of our invention is added to the extruder at one or more barrel segments S-3, S-4, S-5, S-6, S-7 and S-8 of the extruder (which may be a twin screw of single screw extruder) at locations 18a, 18b, 18c and 18d (for example) by means of gear pump 23 from source 17. From source 19 into barrel segments S-5, S-6, S-7, S-8, S-9 and S-10, a gaseous or liquid blowing agent, e.g., nitrogen, carbon dioxide and the like as described, supra, are added simultaneously with the addition of insect attractant, e.g., 2-undecyl acetate or insect repellent e.g., one or more of the ketones, ketoesters or alcohol of our invention. The feed rate range of resin is about 80-300 pounds per hour. The feed rate range of insect attractant or repellent is between 1 and 35% of the feed rate range of the resin. The blowing agent range is such that the pressure of the gas or the pressure over the liquid being fed into the extruder is between about 50 and 200 psig if, indeed, blowing agent is added. If desired the extruded ribbon or cylinder may be passed through water bath 20 and pelletizer 21 into collection apparatus 21a.

A preferred embodiment of our invention comprises an ellipsoidally-shaped detergent tablet 830 containing a solid plastic core 832 which can be fabricated from, for example, polyethylene, polypropylene, nylon or any polymer capable of having therin microvoids from which an insect repelling substance, e.g. trans, trans-delta-damascone will be controllably transported from the plastic core into and through the soap cake over a reasonable period of time during the use of the soap cake. Such polymers can be microporous polymers such as those described in U.S. Pat. No. 4,247,498 issued on Jan. 27, 1981, the specification for which is incorporated herein by reference. Surrounding the central plastic core containing insect repellent 832, is detergent 830' which is in the solid phase at ambient conditions, e.g., room temperature and atmospheric pressure. Examples of workable detergents 830' are "elastic" detergents such as those described in U.S. Pat. No. 4,181,632 issued on Jan. 1, 1980, the disclosure of which is incorporated herein by reference, or "transparent" soaps such as those set forth in U.S. Pat. No. 4,165,293 issued on Aug. 21, 1979, the disclosure of which is incorporated herein by reference. Other examples of the detergent 830' useful in our invention are those set forth as "variegated soaps" in Canadian Letters Patent No. 1,101,165 issued on May 19, 1981, the disclosure of which is incorporated by reference herein.

On use of the soap tablet 830 or detergent bar, the insect repellent agent originally located in plastic core 832 is transported at a steady state from core 832 through core surface 831 through the detergent 830' and finally through the surface of the detergent bar at, for example, 833, 834, 835 and 836.

The detergent bar or tablet 830 of our invention may be of any geometric shape, for example, a rectangular parallelepiped tablet as shown in FIGS. 51, 52 and 53 containing solid plastic core 839. The insect repellent located in solid plastic core 839 on use of the detergent bar passes through at steady state surface 837 of FIG. 52, detergent 838 and finally surface 839 at, for example, locations 840, 841, 842 and 843. The environment surrounding the detergent bar on use thereof is then treated with the insect repellent at 843, 844 and 845, for example. Optionally, aromatizing agent can also be contained in the detergent bar and so the environment surrounding the detergent bar on use thereof would also be aesthetically aromatized at 843, 844 and 845, for example.

As is shown in FIGS. 54, 55 and 56 the plastic core of the detergent tablet 830 may have a single finite void at its center 851 (of FIGS. 55 and 56) in which the insect repellent agent and optionally the aromatizing agent is contained. The plastic core then is a shell 848 having outer surface 852 (shown in FIGS. 55 and 56). The insect repellent agent (and optionally the aromatizing agent) contained in the void in the plastic core permeates through shell 848, past surface 852 at a steady state, through the detergent 847 and to the environment at, for example, 856, 857, 858 and 859.

In addition to the insect repellent contained in the core, e.g. core 839 or core void the core can also contain other materials for therapeutic use, for example, bacteriastats, deodorizing agents and the like which are compatible with insect repellants such as the ketones, ketoesters and alcohol of our invention In the alternative, the plastic core of the detergent tablet of FIGS. 54, 55 and 56 may have an empty single finite void at its center 851 with the insect repellent contained in the shell 848.

At the end of the use of the detergent tablet, the hollow core or the solid core can be used as an insect imparting and aroma imparting or air freshener household article In addition, depending on the ratio of the volume of the void 851, to the solid part of the detergent tablet of FIGS. 54, 55 and 56, the detergent tablet of FIGS. 54, 55 and 56 can be so fabricated that it will float on the surface of the liquid in which it is being used and this physical attribute has certain obvious advantages.

Paraffin was is intimately admixed at 150° C. and 10 atmospheres pressure with 1-octen-4-ol in an autoclave with intensive shaking. The autoclave pressure is maintained with a nitrogen atmosphere. At the end of the period of one hour, the autoclave is depressurized, the autoclave is opened and the resulting mixture is poured into cylindrical candle molds containing wicks.

The resulting candles on use evolve an aesthetically pleasing aroma and, in addition, give rise to efficacious house fly repellency. The candles are effective in preventing house flies from entering a room in which one candle is burning for a period of 10 minutes, the said room having the dimensions 6'×15'×15' having a 3'×3' open portal adjacent to a house fly-infested region in the month of July in the temperate zone (location: Highlands, N.J. next to Raritan Bay).

All of the materials except the polyamide are mixed at room temperature. The mixture is then heated gradually with gradual addition of the polyamide and with agitation beginning with the commencement of addition of the polyamide. In the proportion required, the polyamide does not become fully soluble until the mixture reaches the temperature of about 220° F. The temperature on the order of 220° F. to 230° F. is maintained at atmospheric pressure with continued agitation until the polyamide is fully dissolved. Since higher temperatures promote solution of the polyamide this temperature range can be slightly exceeded with some advantages.

As soon as the polyamide has dissolved completely, the mixture is poured into molds following the conventional practice in the manufacture of molded candles. As the candles cool they harden. The candles are then freed from the molds and tested for house fly repellency.

The candles are effective in preventing house flies from entering a room in which two candles have been burning for 15 minutes, the said room having dimensions of 6'×15'×15' and having a 3'×3' open portal adjacent a house fly-infested region in the month of July in the temperate zone of Highlands, N.J. adjacent Raritan Bay.

EXAMPLE IV

A study was conducted to evaluate the efficacy of candles which are designated as "A", "B", and "C" in repelling house flies (Musca domestica L.(Diptera:Muscidae)).

Candle "A" contained 95% Paraffin Wax and 5% of 1-octen-4-ol.

Candle "B" contained 90% Paraffin Wax and 10% citronella oil.

Candle "C" contained only Paraffin Wax.

The candles are allowed to burn for 20 minutes and the number of house flies repelled is recorded for the next 60 minutes with the following equipment and procedure:

Materials Test Chamber

The evaluation was conducted in a 28.3 cubic meter chamber with airing ports A screened cage measuring 15 cm×15 cm×47.5 cm was attached inside an upper airing port, and a screened repellency observation cage measuring 15 cm×15 cm×32.5 cm was attached outside the upper airing port. The two cages were held together by a Masonite plate which fit firmly in the airing port. A 4-cm hole located in the center of each Masonite plate provided an escape for the test insects. A barrier was used to close the hole.

Attractant

A caged mouse was used as an attractant and was placed inside the chamber in the larger section of the repellency cage.

Test Insect

Adult house flies (Musca domestica) are test insects.

Procedure

For each replicate, 75 to 100 adult house flies were removed from the rearing cage by means of a vacuum aspirator, and transferred by carbon dioxide anesthesia to the inner cage containing the mouse. The assembled cage was placed in one of the upper ventilation ports of the chamber For each experimental situation the test insects were transferred to a clean cage containing the mouse. A house fly candle was placed centrally on the chamber floor and burned for 20 minutes before initiating the repellency counts. The maximum period for the repellency counts was 60 minutes. The first repellency count was made at 10 minutes after the burning ended, and subsequent counts were taken at 5-minute intervals thereafter. The number of house flies repelled were those escaping to the outside cage. For the control, counts were made in a similar manner, but no candle was burned.

The same three candles were used for all fours replicates Between replicates the chamber was exhausted, the Kraft paper flooring for the chamber was replaced, and the two screened repellency cages were submerged in hot detergent water, rinsed and dried.

RESULTS

The overall average percent of house flies repelled for each candle for 60 minutes was as follows

Candle "A" 88%

Candle "B" 52%

Candle "C" 16%
